hi ive been on 30mg of citalopram for years and recently its not as effective as it normally is. anxiety came flooding back and just feeling awful. i went to the doc who upped my dose to 40mg this was 6 days ago. i did have a few mild side effects mainly feeling dizzy and sick. my question is has anyone else gone from 30mg to 40mg and found it helped and how quickly it helped. I have got myself in a right state thinking how can going up by 10mg help me.
